People who dont pay!

This is about those customers who don’t pay! I’m sure I’m not the only one who is experiencing this problem! I wouldn’t mind if the job was shoddy or just bad workmanship but i have a testimonial from my customer! There is the usual route to go i.e send in the debt collectors but my own views on this are well known! Letter writing, this is where you send the first letter saying how you are sure your customer as “forgotten to post the cheque” only to find that after 7 days they have still forgotten, so you send the second letter which is a bit more stern, Something like, We notice you still have NOT paid “you got 3 days” A week later, NOTHING! Now its time for THE letter” which simply says, pay now or this go’s to our solicitors!! There’s something about that letter that makes me feel bad and keep putting off sending it, Don’t know what it is cant quit put my finger on it, I have come to the conclusion that from now on everyone i do work for must pay when the job is complete!
